Introduction
Join the Geodetic Metrology group at CERN, to develop new alignment methods and tools for the Future Circular Collider (FCC) study. You will be part of the team in charge of the development of the R&D for the next generation of colliders. You will actively contribute to build, integrate and support the wide range of computing tools used for metrology and alignment at CERN, with a focus on the theoretical aspects related to the statistical data processing of survey data, the development of mathematical concepts and the proposition of new algorithms responding the future project needs. You will collaborate with other research teams, inside and outside CERN, to benefit from the latest developments in this field. Take part!
Functions
As a mathematician:
- You will be part of a research team that develops innovative measurement techniques and new instruments for the next generation of colliders. You will take into account their latest experimental results to elaborate the mathematical models that accurately describe the behaviour of new devices and sensors.
- You will study more complex measurement systems combining different techniques and types of instrumentation, and you will establish corresponding theoretical models. You will thus contribute to optimizing the configuration of these future measurement systems and finding the best compromises with different experts. You will carry out the complete simulation of different measurement system solutions and evaluate their effectiveness in terms of expected accuracy, reliability criteria and robustness analysis.
- You will develop and apply parameter estimation techniques, including least squares, L1 norm minimization, and Huber estimation.
- You will address future challenges related to large-scale optimization, developing scalable solutions that can efficiently handle high-dimensional problems. You will propose innovative solutions to perform the enormous calculations required by simulations, keeping in mind that similar methods could also be integrated into the future operational data processing workflow.
- You will design real-time estimation algorithms with a strong focus on speed and efficiency to meet the demands of time-sensitive applications such as monitoring tasks. You will also have the opportunity to partly implement some of the most promising results from your studies into today's survey data processing workflow.
- You will present optimization results and insights to various audiences, including surveying engineers, software experts, and non-expert stakeholders, ensuring that the implications and benefits are clearly understood. You will tailor communication to effectively convey complex mathematical concepts to both technical and non-technical audiences.
Master's degree or PhD or equivalent relevant experience in the field of Applied Mathematics, Geodesy or Geomatics, with a focus on optimization and parameter estimation or a related field.
